Intelligent plug principle
Intelligent plug is a new type of safety socket which integrates PLC automatic control safety and energy-saving converter and intelligent standby power-saving socket for electrical appliances. Its working principle is that when the power supply is turned on by infrared induction, the electrical appliance begins to be used normally. By embedding the intelligent IC chip into the socket, the current change can be automatically detected online, so as to realize the standby and automatic power-off of the electrical appliance after a period of time (30 seconds, 5 minutes, 30 minutes, etc.). ), and the problem of standby energy consumption can be completely eliminated.
In addition, the smart plug also has the functions of lightning protection, high voltage protection, overload protection and leakage protection. The intelligent plug can automatically absorb the high voltage induced by lightning. If the high voltage induced by lightning exceeds the range that the socket itself can absorb, the socket will automatically cut off power. The rated voltage of the smart plug is 220V, and the maximum withstand voltage is between 250 V and 265 V. If it exceeds this voltage range, it will automatically cut off power. Intelligent plug uses electronic coil to monitor the fire line in real time. In case of overload and leakage, the socket will automatically cut off power.
Main functions of intelligent plug
1. Sockets are divided into "master" jacks and "controlled" jacks.
2, static, that is, when the socket is not in use, the socket has no power output, and the working indicator light of the socket is not on at this time, which is in a state of no power. At this time, the electrode in the socket is completely disconnected from the power supply, and the safety is high.
3. After receiving the infrared signal, the socket will automatically turn on the power supply, so that the electrical appliance can be used normally.
4. After the electrical appliance is turned off, the intelligent dual-core IC chip inside the socket will detect the current change online, thus automatically turning off the power supply after a period of time (30s, 5min, 30min, etc.). ). At this time, the working indicator light on the socket goes out, and the power-off state is restored.
5. The smart plug has the functions of lightning protection, high voltage protection, overload protection and leakage protection. Once the lightning-induced high voltage enters, the socket will automatically absorb the lightning-induced high voltage, and if it exceeds the scope that the socket itself can absorb, the smart plug will automatically cut off power; The rated voltage of the socket is set to 220V, and the maximum withstand voltage is between 250 V and 265 V, which will automatically cut off the power, otherwise the electrical appliances with voltage exceeding this range will be burned out; The socket uses electronic coil to monitor the live wire in real time. Once it is overloaded, the intelligent plug will automatically cut off the power supply. Smart plugs use electronic coils to check live and neutral currents, and sockets will automatically cut off power supply in case of leakage.
Types of smart plugs
The main function of smart plugs is energy saving and environmental protection, which can be roughly divided into the following three types according to their respective emphases and different designs:
1, metering socket: it can directly reflect the working power, current, voltage and other information of electrical appliances on the socket. But only users can know the electricity consumption of electrical appliances, and users with certain professional knowledge can find out whether the electrical appliances are using electricity normally according to the measurement results.
2. Timed socket: It can control the electrical appliances to work in a specific period of time, which reduces the energy waste in idle period to some extent. However, the actual power consumption cycle is not fixed, and it is inconvenient to use once the situation changes and needs to be reset.
3. remote control socket: It needs to be equipped with a dedicated remote controller, which is expensive and difficult for many users to accept.
Smart plug brand
1, broadlinkSP 1:Broadlink smart plug sp 1 has a universal jack on the front, which is compatible with plug standards in most parts of the world, and a national standard three-pin plug on the back. There is a small button and two LED indicators on the right side of the switch to indicate the Wi-Fi status (yellow light) and the power-on status (green light) respectively. Connect wifi to download APP and related appliances, which is simple, convenient and cost-effective.
2.Belgin: Belgin has been listed as one of the 500 fastest-growing private enterprises in the United States by Inc. magazine twice, and it is the company with the largest sales volume of IT accessories in the United States. There are four types of products with the largest market share in the United States, including cable market share of 83%, surge-proof power supply of 54%, USB hub product of 68% and KVM product of 63%. Belgin's WeMo modular smart home remote control system, combined with WEMO sensor, can realize the functions of turning on the light when entering the room or turning off the fan when leaving the room.
3. Poly Home: Poly Home Smart Plug is one of the smart home products produced by Beijing Boli Heng Chang Technology Co., Ltd. ... The embedded Zigbee wireless receiving module can remotely control and intelligently control some household appliances, such as on-off air conditioners and on-off rice cookers. , and can also be interchanged with ordinary sockets.
4. Clean room: intelligent safe and environmentally friendly converter ZN-6W0 1 adopts artificial AI principle to intelligently control the turn-off of TV, DVD, power amplifier and stereo. Just switch the computer host or TV, and the corresponding peripheral devices will automatically turn on or off. When the host computer or TV set is not working, it will automatically cut off the total power supply of all equipment. All these tasks are automatically controlled by the intelligent module in the socket.
In addition, big brands at home and abroad, such as Siemens, Panasonic and Meilan Rilan, have gradually entered the smart plug market. They have their own characteristics and are good creative products in home life.
